In the title compound, 2C(8)H(20)N(+)·2C(4)H(5)O(6) (-)·C(4)H(6)O(6)·H(2)O, the presence of the two tetra-ethyl-ammonium cations is balanced by two hydrogen l-tartrate anions. Also present in the asymmetric unit are a mol-ecule of l-tartaric acid and a water mol-ecule. The various components are linked by O-H⋯O hydrogen bonds. In the crystal, two-dimensional networks are formed via O-H⋯O hydrogen bonds and C-H⋯O inter-actions involving the water mol-ecule, the hydrogen l-tartrate anions and the l-tartaric acid mol-ecules. These layers, which stack along [001], are separated by tetra-ethyl-ammonium cations. The latter are also involved in C-H⋯O inter-actions with the anions and the l-tartaric acid and water mol-ecules participating in the two-dimensional network.
在标题化合物2C₈H₂₀N⁺·2C₄H₅O₆⁻·C₄H₆O₆·H₂O中，两个四乙铵阳离子由两个左旋酒石酸氢根阴离子平衡。不对称单元中还存在一个左旋酒石酸分子和一个水分子。各种组分通过O—H⋯O氢键相连。在晶体中，通过涉及水分子、左旋酒石酸氢根阴离子和左旋酒石酸分子的O—H⋯O氢键和C—H⋯O相互作用形成二维网络。这些沿[001]堆积的层被四乙铵阳离子隔开。后者也参与与二维网络中的阴离子、左旋酒石酸和水分子的C—H⋯O相互作用。
